Some nights you want the cozy, creamy comfort of chicken pot pie, but you don’t have the time or patience to roll out pie dough.
This chicken pot pie casserole recipe gives you that same warm, savory filling under a golden biscuit topping, and it comes together with about 20 minutes of hands-on work.
No crimping a crust, no blind baking, just one dish that tastes like a hug.
This is a from-scratch recipe, but “from scratch” doesn’t mean complicated here.
You’re working with a simple roux-based filling, frozen mixed vegetables to save chopping time, and canned biscuits for the topping unless you want to make your own.
It’s the kind of dinner that reheats well too, so it’s worth doubling if you’ve got a busy week ahead.
Chicken Pot Pie Casserole (Easy Comfort Food Dinner)
This chicken pot pie casserole has all the cozy comfort of the classic, minus the fuss of a pie crust. A rich, creamy chicken and vegetable filling bakes right under golden, buttery biscuits for a dinner that's warm, hearty, and easy enough for a weeknight.
Ingredients
- 3 tablespoons butter
- 1 small yellow onion, diced
- 2 carrots, diced
- 2 celery stalks, diced
- 3 cloves garlic, minced
- 1/3 cup all-purpose flour
- 2 cups chicken broth
- 1 cup milk
- 3 cups cooked, shredded or diced chicken (rotisserie chicken works great)
- 1 1/2 cups frozen peas and corn
- 1 teaspoon dried thyme
- Salt and black pepper, to taste
- 1 can (16.3 oz) refrigerated biscuits, or 1 batch homemade biscuit dough
- 1 tablespoon melted butter, for brushing
Instructions
- Preheat the oven to 375°F. Grease a 9x13-inch baking dish.
- Melt the butter in a large skillet or Dutch oven over medium heat. Add the onion, carrots, and celery. Cook for 5 to 6 minutes, until the vegetables start to soften.
- Add the garlic and cook for 30 seconds, until fragrant.
- Sprinkle the flour over the vegetables and stir to coat. Cook for 1 minute, stirring frequently, to remove the raw flour taste.
- Slowly pour in the chicken broth while stirring, then add the milk. Keep stirring until the mixture thickens, about 4 to 5 minutes.
- Stir in the chicken, peas, corn, thyme, salt, and pepper. Let it simmer for 2 minutes, then pour the filling into the prepared baking dish.
- Arrange the biscuits over the filling, leaving a little space between each one so they have room to puff up.
- Brush the biscuit tops with melted butter and bake for 20 to 25 minutes, until the biscuits are golden brown and the filling is bubbling at the edges.
- Let the casserole rest for 5 minutes before serving.

Ingredient Swaps
Chicken pot pie casserole with noodles: Skip the biscuits and stir in 2 cups of cooked egg noodles into the filling, then top with a simple breadcrumb-and-butter mixture before baking. It turns the dish into more of a creamy chicken noodle bake.
Cheddar bay biscuit topping: Swap the plain refrigerated biscuits for a box of cheddar bay biscuit mix, or stir 1/2 cup shredded cheddar and a pinch of garlic powder into your biscuit dough before topping the casserole.
Rotisserie chicken shortcut: A store-bought rotisserie chicken saves a step and adds good flavor. One chicken usually gives you more than the 3 cups you need here, so save the rest for lunches.
Healthy swap: Use low-sodium chicken broth, replace the milk with unsweetened almond milk, and add an extra cup of chopped vegetables, such as mushrooms or green beans, to bulk up the filling with minimal extra effort.
Make It in the Crockpot
You can make the filling in a slow cooker if you’d rather not stand at the stove.
Add the raw vegetables, garlic, broth, chicken, and seasonings (skip the flour and milk for now) to the crockpot and cook on low for 5 to 6 hours, or until the vegetables are tender.
About 30 minutes before serving, stir in a slurry of 1/3 cup flour whisked with the milk to thicken the filling, then transfer everything to a baking dish, top with biscuits, and bake at 375°F for 20 minutes to brown the topping.
Freezer Meal Instructions
This casserole freezes well, which makes it a solid freezer meal for a stocked-up freezer.
Prepare the filling as directed, let it cool completely, and freeze it in a labeled freezer-safe container or bag for up to 3 months.
Add the biscuit topping fresh the day you bake it rather than freezing it pre-assembled, since frozen biscuits tend to bake unevenly.
Thaw the filling in the fridge overnight, then top with fresh biscuits and bake as directed, adding a few extra minutes if the filling is still cold in the center.
FAQ
Why is my chicken pot pie casserole filling too thin?
This usually means the roux didn’t cook long enough or the flour wasn’t fully whisked in before adding the liquid.
Let the filling simmer a few extra minutes on the stove.
It will also thicken more as it bakes.
Can I use canned vegetables instead of frozen?
Yes, drained canned peas and carrots work in a pinch, though frozen vegetables tend to hold their texture a little better and taste fresher in the finished casserole.
Can I make chicken pot pie casserole ahead of time?
Yes. Make the filling up to 2 days in advance and store it, covered, in the fridge.
Add the biscuit topping right before baking, so it bakes up fresh and golden instead of getting soggy.
Is this recipe kid-friendly?
Most kids like the creamy, mild filling and the biscuit topping.
If your kids are picky about vegetables, dice the carrots and celery smaller, so they blend into the sauce.
Can I make it healthier?
Yes, see the Healthy swap listed above.
Using low-sodium broth, a lighter milk option, and extra vegetables keeps the flavor while lightening it up a bit.
How do I store and reheat leftovers?
Store leftovers covered in the fridge for up to 4 days. Reheat individual portions in the microwave, or cover the dish with foil and reheat in a 350°F oven for about 15 minutes to keep the biscuits from drying out.
Can I double this recipe?
Yes, this recipe doubles well in a 9×13-inch dish if you use a deeper dish, or split it across two dishes.
Just note the bake time may run a few minutes longer since the filling layer is deeper.
Conclusion
When you’re craving cozy comfort food but don’t have it in you for an all-day cooking project, this chicken pot pie casserole is the answer.
The filling comes together on the stovetop in under 15 minutes, and swapping pie crust for biscuits means less fuss and just as much flavor.
Try it once with the classic biscuit topping, then experiment with the cheddar bay version or the noodle swap next time. However you make it, it’s worth keeping in the regular dinner rotation.
